SPECIFICATION forming part of Letters Patent No. 607,382, dated July 12, 1898.

Application filed August 28, 1897. Serial No. 649,810. (No model.)

To (LZZ whom it may concern.-

Beit known that I, JOHN H. KOONS, of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Screens for Doors or WVindows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in screens for doors and windows.

The object of the invention is to provide simple and highly efficient means for securing a screen within a door or window frame and also to insure the egress of flies on the inner face of the screen and at the same time prevent their ingress from the outside. These objects I accomplish by providing the inner faces of the upright of a frame with diagonally-arranged grooves which receive and accommodate the side edges of the screen,whereby overlapping portions of the screen form guideways or chambers up into which the flies will rise. Atthe apex of each overlapping portion forming a chamber are formed holes or openings through which the flies will egress. These holes are formed by cutting two intersecting strands of wires, the ends of which are bent outward, permitting the egress of the flies, but preventing their ingress from the outside of the screen. The upper crossbar of the frame is provided with a series of inclined openings over which the screen extends, leaving sufficient space at the upper end for the exit of flies and the like.

The invention will be hereinafter fully set forth, and particularly pointed out in the claim.

In the accompanying drawings, Figure l is a view in elevation. Fig. 2 is a vertical sectional view on line 2 2, Fig. 1. Fig. 3 is an enlarged view in detail of a portion of the screen.

Referring to the drawings, A designates a frame composed of upperand lower horizontal members a a and side uprights a In the inner opposite faces of these uprights a are formed obliquely-arranged grooves d, all of which are parallel and at an angle of about sixty degrees.

The result is the same as if a side passing in through the latter.

, ends should be secured to the innerside of said uprights.

B is the screen, the side edges of which are secured first to the outer face of the frame and then carried inward and downward in the uppermost groove h, and then down the front face of the frame, and thence upward through the second groove to the upper end of the latter, and then brought straight down over the outer face of the frame, and so on to the lower crossbar a. In passing the screen upward and outward through one of these small grooves cl and then downward chamber-like spaces 1) are formed, into which flies walking upward on the screen will enter.

In the extreme apex of each bent portion of the screen forming these chambers two or more small holes b are made by cutting two intersecting wires. These holes are not made smooth or perfectly round; but the cut ends of these wires are slightly bent outward in such manner as to permit of the flies on the inner side of the screen passing out through said holes, but preventing flies from the out- The projecting ends of the cut wires will retard this ingress of the flies.

The upper cross-bar a of frame A is formed with a series of spaced-apart tapering grooves 12 through which flies can pass out from on the inner face of the screen. The screen B is secured to the faces between these tapered grooves, but sufficient space is left between the upper edges of the screen and the upper edge of each tapered groove.

From what has been said it will be seen that I have provided an extremely simple having inclined recesses in its outer face, and tersecting strands of the netting-wires, sub- 10 said side uprights having on their inner, opstantially as and for the purpose set forth. posite faces inclined grooves, and aWire-net- In testimony whereof I have signed this ting secured to the said upper cross-bar and specification in the presence of two subscribextended over portions of said recesses, the ing witnesses.
